Vector Shoreline of Rota from IKONOS Satellite Imagery, 2002

IKONOS satellite imagery was purchased to support coral mapping and GIS projects in the Pacific Islands. A digital vector shoreline for Rota was manually digitized from one-meter panchromatic imagery to provide accurate data. The dataset originates from NOAA NCEI and was last updated in November 2001.

Use Cases

• Coastal change detection and monitoring based on the manually digitized, high-resolution shoreline.
• GIS base layer creation for environmental planning based on the accurate, up-to-date vector data.
• Coral reef habitat mapping support based on the imagery's use for National Ocean Service activities.
• Shoreline accuracy assessment for other datasets based on the one-meter panchromatic source.

Strengths

• Derived from one-meter resolution panchromatic IKONOS imagery, suggesting high spatial detail.
• Manually digitized to provide accurate shoreline data, as stated in the description.
• Created to support specific NOAA coral mapping and Pacific Islands GIS projects.

Limitations

• Last updated 2001-11-19 00:00:00; freshness should be verified.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and file size are unknown, which may limit suitability assessment.
